Appendix F: Eagle Tank Tester Model
The Eagle Tank Tester model is intended for checking tanks or vessels
that may contain residual hydrocarbon vapors or water or may have
been purged of oxygen. You can also use this model as a standard
Eagle gas monitor by connecting the standard hose and probe and
updating the oxygen alarms to the default settings.
Description
The tank tester model has an additional socket on the front on the
housing to accommodate connection of the float probe assembly. This
model includes the following non-standard components.
Float Probe Assembly
The float probe assembly helps prevent liquid from being drawn into
the Eagle. The float probe assembly is 12-feet long. A quick disconnect
fitting at one end of the assembly connects to the Eagle’s inlet fitting.
The same end of the probe also includes a short wire that terminates
in a jack. This jack connects to the float probe socket that is adjacent to
the Eagle’s inlet fitting. The float probe switch at the opposite end of
the 12-foot cable shuts off the pump if the probe begins to be
submerged into a liquid.
To use the float probe assembly:
CAUTION: Drawing water, gasoline, or other liquids into the Eagle will
cause damage.
1. Attach the quick disconnect fitting to the Eagle’s standard inlet
fitting.
2. Attach the jack to the socket that is adjacent to the inlet fitting.
3. Lower the probe into the tank or vessel. Lower the probe very
slowly to allow the float switch to activate if necessary.
Dilution Fitting (1:1)
CAUTION: When measuring oxygen readings, remove the dilution fitting
or use your finger to seal the small dilution hole on the side of
the dilution fitting.
The standard combustible gas sensor requires oxygen to operate. In
environments where there is not enough oxygen to operate the
combustible gas sensor, (for example a tank purged with an inerting
gas), the 1:1 dilution fitting adds sufficient oxygen by blending
